Abstract

An image signal processing method is disclosed for maintaining high image display quality by avoiding signal-mode misjudgment. The image signal processing method includes generating a first threshold based on a plurality of motion values generated prior to a first time when an image input signal is detected to be of a film mode, generating a second threshold based on the first threshold and a first offset, generating a third threshold based on the first threshold and a second offset, and determining whether the image input signal between the first time and a second time is the film mode or a video mode based on the second and third thresholds.
